4 SPECIFICATION forming part'of Letters Patent No. 324,828,dated August25, 1885.

I Application filed October 13, 1884'. (No n1odel.)

i .To all whom it may concern.

Be it known that. I, OSCAR GASSETT, of Boston, countyof Suffolk, Stateof Massatfiusetts, have invented an Improvement in otor-PressureGenerators, of .which the following description, in connection with theaccompanying drawing, is a specification, like let ters on the drawingrepresenting like parts.

My invention relates to an apparatus for generating fluid-pressure whichmay be employed in actuating mechanical motors or engines. v

The invention consist-s,es'sentially, in ap'paratus for the-combustion,in a confined space or chamber, of a combustible vapor or gas, the gasesor heated products of combustion from which may be employed toact-uate'by their pressure or expansion an engine or motor of anysuitable or usual construction.

The invention is embodied in an apparatus consisting, essentially, of astrong tight cham ber, shown astubular or cylindrical in shape, and asecond closed chamber, shown as contained within the main chamber, thesecond or, internal chamber, whilethe apparatus is in operation, beingexposed to the action of a flame,by which it is heated to ahightemperature. The said internal chamber is supplied with w ater, which isconverted into steam th are in, andtthe steam is employed in connectionwith-a reservoir containing a combustible liquid-such, for instance, asthe usual hydrocarbon compounds-#0 produce a jet of inflammato be set inoperation.

ble' gas or vapor, which is ignited and produccs a flame, by which thesaid .chamber is heated to generate the steam. Suiticient air,preferably also heated by the flame, is supplied to support combustion,and the combined heat combustion of the hydrocarbon liquid with steamand air may be employed to actuate a mechanical motor or to perform workby their pressure and expansion.

Appliances are provided for producing steam in order to start the flame,and also for igniting the saidflame when the apparatus is longitudinalsection under press The heated The drawing shows in an apparatus forgenerating gases ure embodying this invention.

and expanded gases are containing oil or other gases or products derivedfrom't-he before described.

generated in a main be of any chamber or reservoir, (4, which maysuitable size and shape. chamber, 1), of cast or malleable iron, isshown as contained within the main chamber, and

when the apparatus is in operationwill contain steam under highpressure, generated as hereinafter described, and the said conveyedtherefrom through a pipe, .2, to a nozzle or injector apparatus, d, fromwhich it issues with greatvclocit-y and operates in the well-knownmanner to reduce the pressure in a pipe, 6, communicating with areservoir, f, hydrocarbon fluid, which, when combined with steam andair, producesa combustible gas or vapor. 'The' flow of combustibleliquid through the pipe 6 is controlled by a cock or valve, 9, sothatthe proper amount may be combined with the issuing jet of steam,producing a combustible compound, which, when ignited, will burn with aflame that acts upon the internal chamber, b, heating it sufiicicntly tomaintain the generation of steam therein aslong as a suflicientsupply ofwater is kept up. Air is admitted to the nozzle (1 in sufficientquantities to support combustion of the gaseous jet A steam-generatingsteam is I issuing from-the'fiozzle d through a pipe, It,

the said air being forced in under pressure, if necessary. The pipe h,preferably, is also ex: posedto the action of the flame, as shown, sothat it combines with the inflammable gas or vapor-in a highly-heatedcondition, More air may be admitted essary, the amount being cont-rolledby a suitable: register.

In'orde to provide steam in the chamber b for producing the jet atfirst, before the flame has heated the chamber 1), an auxiliary Stealnfgenerator, 70, her I) by pipes m and by a'suitable valve, 0,

a, the latter controlled the said auxiliary generator kbei'ng heated inany suitable manner, as by the flame of a lamp,or alcohol contained in asaucer or chafing-dish, k, for small appa f ratus, until steam isgenerated therein at sufficient pressure,

whenthc said steam will flow through the pipem to the chamber 1) and pipc 0, when it will produce the combustible jet, as I The said jet thusproduced is connected with the said cha'mthrough an opening, i, ifnecmay be ignited in any suitable manner. As

shown in this instance, the igniting device consists of a loop, a offine platinum wire mounted on a spindle, 12 provided with a suitablehandle, 2', by which it may be turned from the outside of the chamber a,the said loopp being connected in circuit with a suitable battery orgenerator of electricity, B. When the flame has been burning for a shorttime, the chamber b will be sufficiently heated for the generation ofsteam therein, after which the heat may be removed from the chamberk andthe "alveo opened, admitting water to the chamber b in sufficientquantities to maintain the jet in constant operation. The pressure inthe chambers b and k is equalized by the steam passing through the pipem to the upper portion of the chamber k, so that the water will flow tothe chamber b by gravitation; its amount being regulated by the valve 0.The flame burning at d produces gases at a very high temperature, which,when confined, as in the chamber a, are under suflicient pressure toactuate a motor, the said gases being conveyed from the reservoir a tothe said motor, where they expand, and, in partiugwith their heat,produce mechanical work. But a very small amount of steam is required toproduce the proper jet atthe nozzle (1', and as more steam may begenerated in the chamber b, the surplus may be discharged through apipe,p, terminating in'a nozzle within a concentric nozzle, r, connected witha partition, t, in the chamber a, so that the jet of steam issuing fromthe pipep will tend to force the gases from the side of the partition t,where they are generated, into-the portion a of the'chamber in advanceof the said partition, where the pressure will be greater, and fromwhich the mingled steam and gas may be taken to supply the engine. Acheck-valve, t, in the partition i permits the gases to flow into theportion a of the chamber when no steam is issuing from the pipe 1), sothat the pressure is nearly equal on both sides of the partition. Vfhcnthe chamber k is nearly emptied of water, an additional supply may beintroduced without interrupting the feed to the chamber' b by means of achamber, k, the lower portion of which is connected with the chamber kby a pipe, n, containing a cock, n". The upper portion 0f.,the chamber1: is connected by a pipe, m, containing a cock, m, with the pipe an,communicating with the'steam-chamber b and upper part of the chamber k.When the cooks n 11: are closed, the chamber k is cut off from thechambers k and b, so that the said chamber k may be readily filled.Then, by.

(losing the inlet to the chamber In and openi ng the cooks m n,- thesteam-pressure in the chambers k and is will be equal, and the waterwill flow by gravitation from the chamber k into the chamber k. Thechamber a may be provided with an outlet-pipe, u, controlled by a valve,u, which may be opened when the apparatus is being first set inoperation, in

order to atford a read escape for the products of combustion, so thatthere will be no pressure to resist the entrance of air and combusti bleliquid until the combustion is thoroughly under way. Aremovable plate orbonnet, I, may be provided for affording access to the nozzle d, and thesaid plate may be removed for the purpose ofigniting the flame, ifdesired. A block, w, of refractory material will preferably be placed inthe path of the flame issuing from the nozzle d, the said block becomingvery highlyheated, and thus retaining sufiicient heat to ignite thegaseous jet after a momentary interruption in the flow of the gas, incase one should occur. The block 10 is provided with a hole for thepassage of the flame through it.

I claim- 1. In an apparatusfor generating gases under pressure, thecombination of the following elements, namely: the main casing orchamber for containing the gaseous products, a steamgenerating chamber,a reservoir for combusti-' ble fluid, and a nozzle communicating withthe steam-generating chamber, the jet of steam from which nozzle acts onthe fluid supplied from the reservoir, whereby in the operation of theapparatus a jet of combustible gas or vapor is produced, the flame ofwhich acts upon the steam generating chamber, substantially asdescribed.
